I have had several Sonicare brushes over the years, and have always enjoyed quality brushing and teeth cleaning. This Sonicare is no different; it provides a great teeth brushing/cleaning experience at a very affordable price. It is not one of the fancier units that have various settings, but it certainly does the job for me. The only downside is the charging base. The unit I purchased came with a USB charging base. I do not have a practical way of charing using this method, so I must use the traditional 110v wall plug. I am hoping Philips can provide this. The listing did not mention the USB charger when I purchased. I also found out that this particular model is discontinued by Philips (listing said it was not discontinued)
